The electricity market in Great Britain is entirely privatized and liberalised, meaning that there is full competition between private companies. The electricity industry consists of three main parts: 1) Generation (making electricity); 2) Networks (transporting it from where it is generated to where it is used); 3) Supply (selling it to the end consumer)

The BSC Change process is used to progress changes to the BSC arrangements in response to any concerns, problems or defects that Parties may identify in the current processes. Under these processes, changes can be made to the Balancing and Settlement Code, its Code Subsidiary Documents and to BSC Systems.

A CP is a detailed proposal which is raised in order to amend CSDs and/or BSC Systems, but would not alter the BSC. A CP must have a clear aim, a single defined solution and contain the relevant redlined documentation changes.

The Releases process is part of the BSC change procedure and includes information about where changes are being introduced, how they impact on certain areas of the industry and whether your systems will need to undergo tests to ensure they are up-to-date and meet required standards.

This page lists all Consultations relating to Operations and Settlement. The consultations allow ELEXON to gather feedback from the industry about proposed changes so that any concerns are considered as part of our processes.

Electricity is traded in a wholesale market, with generators and suppliers entering into contracts with each other for every half hour of every day; sometimes years in advance. Non-physical traders such as investment banks also participate in this trading.

Balancing Mechanism (BM) Units are used as units of trade within the Balancing Mechanism. Each BM Unit accounts for a collection of plant and/or apparatus, and is considered the smallest grouping that can be independently controlled.

Metering Systems accurately record the flow of electricity to (an Import) or from (an Export) a site. ELEXON uses Metering System data to calculate energy imbalance charges. These charges are applied to BSC Parties who use more or less energy than they have contracted to buy or generate.
